Take a look at the second picture: All the CT cables are carefully formed, the CTs are evenly spaced, the service conductors are neatly arranged. It almost seems like this work was done by someone who was at least trying to take pride in their work, but they'd only been trained to the crippling standard of quality we see in the rest of these photos.

Exactly my impression! American enclosures, British color coding, and a little local variation thrown in for good measure.

Yeah, it must be the colonial influence plus the proximity to the US which results in such a weird system. I'm always amazed by 2nd and 3rd world wiring systems and how we take what we have for granted when it's so much worse elsewhere!

Wow! That's even worse than some of the stuff that I have seen in Mexico. I know that utility companies are exempt from following the NEC here, but I think that their standards are actually higher than what might be required by the code.

That "standard" being used in the photos is nothing short of frightening.
